Anthony could have fed Ashley the "tweaked version" at the request of the jocks. Not a problem, the guy has a brain like a guppy fish, he could have forgotten what he said earlier, it’s strange that he even remembers how to breathe. This is suitable for jocks if there is turmoil in the DIKs and they will be at enmity with each other, looking for a traitor. These jerks will never play fair.
And this would be an obvious set-up for Jacob, because when Derek is in a normal state, he will understand that something is wrong here if the DIKs start blaming MC and read the message again.
